Primary choledochorrhaphy after common bile duct exploration.

AIM: To prove further the safety of primary closure of the common bile duct. METHOD: Twenty patients among 99 common bile duct explorations underwent primary closure. Pre- and postoperative liver function test, ultrasound and intraoperative cholangiography data, operation time, postoperative complications and the length of postoperative stay were recorded. RESULTS: Nineteen patients did not suffer any biliary complication. One had bile leakage and bile peritonitis, and another had duodenal leakage. One case was complicated by gastric ulcer perforation. The mean postoperative hospital stay except for the 2 patients with complications was 8.72 +/- 0.75 days. Preoperative abnormal liver function tests recovered within 2-3 weeks after the operation. Postoperative ultrasound scan of the biliary tract within 2 months revealed no stenosis and residual stone. CONCLUSION: Primary common bile duct closure is a safe alternative to routine biliary drainage in selected patients.

Adrenergic and cholinergic innervation of the common bile duct in men and cats.

To clarify whether or not the common bile duct (CBD) has peristaltic movement, the muscular structure and intrinsic innervation were investigated for the full length of the CBD in 50 fresh human autopsy specimens and 50 cats. Nearly the same results were obtained in control groups of humans and cats. 1) Abundant sympathetic noradrenergic innervation, mainly composed of two plexuses, was demonstrated in each layer of the common bile duct tissue. 2) Parasympathetic nervous innervation was also abundant in each layer of the common bile duct and was composed of two ganglionated cholinergic plexuses. 3) Human and cat ganglia were composed of several nerve cells, which were mostly of Dogiel type II. 4) No other biogenic monoamines than adrenaline (A) and noradrenaline (NA) were detected. 5) Digestive tract hormones were undetectable. 6) The presence of smooth muscle was confirmed all along the common bile duct in all cases. The muscular tissue of the CBD was more abundant in humans than in cats. 7) The results of quantitation of catecholamine and acetylcholine esterase in the common bile duct tissue demonstrated a good correlation between biochemical and histochemical activities.

A non-icteric cholecystectomized patient with recurrent attacks of right epigastric pain and dilated common bile duct--do liver function tests predict bile duct stones?

Cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct are a clinical challenge. In a number of these patients dilatation of the common bile duct is explained as a normal postoperative state following cholecystectomy and the recurrent pain attacks are of origin other than bile disorder, but in some cases dilatation of the common bile duct and attacks are caused by bile duct stones. The aim of the present work was to study the value of common plasma liver function tests in predicting bile duct stones in the group of non-icteric cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct. The study population comprised 24 consecutive non-icteric cholecystectomized patients admitted for elective endoscopic retrograde cholangiopancreatography because of attacks of right epigastric pain and dilated common bile duct in ultrasonography. All the liver function tests seemed to assist in separating patients with bile duct stones (n=11) from those without (n=13). Alanine aminotransferase levels were significantly higher (p=0.05) in patients with bile duct stones than in those without, but also alkaline phosphatase (p=0.07), gamma-glutamyl transferase (p=0.09) and bilirubin (p=0.09) levels seemed to be higher in patients with bile duct stones than in those without, although the differences in these values did not reach statistical significance. In conclusion, common plasma liver function tests assist in separating patients with bile duct stones from those without in this small but clinically important group of non-icteric cholecystectomized patients with recurrent attacks of right epigastric pain and with dilated common bile duct. However, the actual value of these measurements is limited in clinical decision making since overlapping of values occured.

The role of endoscopic therapy in chronic pancreatitis-induced common bile duct strictures.

During endoscopic retrograde cholangiography, common bile duct strictures are encountered in up to 30% of patients with chronic pancreatitis. The indications for treatment of these strictures are discussed. A surgical biliodigestive anastomosis has always been the traditional treatment modality. Not all patients need treatment, however, and endoscopic biliary drainage is the treatment of choice for certain subgroups of patients.

Cholestasis↗

Common bile duct strictures associated with chronic pancreatitis.

Common bile duct (CBD) strictures associated with chronic pancreatitis may cause significant hepatobiliary disease. Nine patients with chronic alcohol-related pancreatitis and CBD obstruction requiring operative biliary or pancreatobiliary decompression are reported. Alkaline phosphatase was the most specific biochemical indicator of cholestasis. Abnormal CBD anatomy was delinated accurately in 89 per cent of cases with percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP). All strictures were localized to the intrapancreatic portion of the distal CBD. Pancreatic pseudocysts (PPC) were identified in six (67%) cases. All nine patients underwent biliary decompression. Simultaneous PPC drainage or pancreatic duct decompression (Peustow procedure) was performed in eight cases (89%). No perioperative mortality occurred, and all patients reported subjective improvement in symptoms. Biliary tract strictures sufficient to cause clinical or biochemical cholestasis are a poorly recognized complication of chronic pancreatitis. Cholangiography (PTC or ERCP) should be obtained in order to delineate radiographic features, and extent and severity of the biliary stricture because there is no predictable correlation between levels of serum alkaline phosphatase and liver histopathology. A percutaneous biopsy is requisite to document changes in hepatic morphology. In order to prevent potential hepatobiliary complications such as cholangitis and secondary biliary cirrhosis, biliary strictures should be managed surgically even in anicteric and otherwise asymptomatic patients. Simultaneous treatment of associated pancreatic pathology can be performed if necessary with little added morbidity.

Imaging of the common bile duct in patients undergoing laparoscopic cholecystectomy.

Options for managing the common bile duct during laparoscopic cholecystectomy include routine peroperative cholangiography and selected preoperative endoscopic retrograde cholangiopancreatography (ERCP). The use of these methods was reviewed in 350 patients with symptomatic gall stones referred for laparoscopic cholecystectomy. Unit A (n = 114) performed routine cystic duct cholangiography but undertook preoperative ERCP in patients at very high risk of duct stones only; unit B (n = 236) performed selected preoperative ERCP on the basis of known risk factors for duct stones. The detection rate for common bile duct stones was similar for units A and B (16% v 20%). In unit A, five of seven patients who had preoperative ERCP had duct stones. Operative cholangiography was technically successful in 90% of patients and duct stones were confidently identified in 13, one of whom went on to immediate open duct exploration. Postoperative ERCP identified duct stones in only four patients, indicating spontaneous passage in eight. In unit B, preoperative ERCP was undertaken in 76 of 236 (32%) patients and duct stones were identified in 47 (20%). Duct clearance was successful in 42 (18%) but failed in five (2%), necessitating elective open duct exploration. Both protocols for imaging the common bile duct worked well and yielded satisfactory short term results.

The selective use of combined supraduodenal and transduodenal exploration of the common bile duct.

The results of combined supraduodenal and transduodenal exploration of the common bile duct in 42 selected cases are presented. The indications for this operation were: the presence of multiple calculi in the common bile duct; stones impacted in the ampullary region; residual stones in the common bile duct following previous surgery on the biliary tract; stricture at the papilla and pancreatitis associated with cholelithiasis. After the procedure no patient had residual stones in the common bile duct. Serious complications were infrequent; there were no postoperative deaths and post-operative pancreatitis occurred in only one patient.

Nonoperative removal of retained common-bile-duct stones.

The discovery of retained common-bile-duct stones after operations on the gallbladder continues to be a frustrating experience for the general surgeon. Until recently this problem was solved in most patients by surgical re-exploration of the common bile duct. However, several alternatives to surgery are gradually gaining acceptance because of their lower morbidity and mortality. These methods are discussed with special emphasis on the use of a catheter with a steering mechanism and the Dormia basket (Burhenne's technique). This is the best alternative to surgery as it has no reported mortality, few complications and causes the least discomfort to the patient. It is highly successful and requires no hospitalization.

Total protein in common duct bile measured by acetonitrile precipitation and a micro bicinchoninic acid (BCA) method.

Bile protein assays are complicated due to interference by other bile substances. In the present study we describe a microtiter plate method for the purification and quantification of bile proteins. The method is based on addition of acetonitrile in three steps to reconstituted freeze-dried bile, followed by ethanol washing of the precipitated proteins. Finally, protein in the precipitate is quantitated by two-point colour development using micro BCA reagents. Overall recoveries of protein in reconstituted bile spiked with exogenous protein (Seronorm) ranged from 91.0% (coefficient of variation; CV = 7.0%) to 97.1% (CV = 2.4%) by recoveries of 125I-Fibrinogen and 125I-Albumin. Bile pigments were largely removed during precipitation and washing, as verified by high pressure liquid chromatography (HPLC). Preferably the samples should be freeze-dried initially, as this lowered the blank readings. Two-point colour development with the BCA reagents were identical for standards assayed directly and standards added to protein depleted bile, and processed through all steps. Hence, no interference by either residual bile constituents nor the reagents upon the BCA protein assay could be detected. Standard curves ranged from 0.05 to 5.0 gl-1 (r > 0.98). Within day reproducibility (n = 15) was 7.8% (CV) and day to day (n = 10) was 12.1% (CV). Mean protein concentration in common duct bile from 30 patients was 1.20 gl-1 (range 0.34-3.87 gl-1). The method appears suitable for assay of bile protein, requires only limited sample volumes and allows processing of many samples within a short time.

Ectopic opening of the common bile duct in the duodenal bulb: clinical implications.

BACKGROUND: An ectopic opening of the common bile duct in the duodenal bulb is extremely rare, and the clinical significance of this anomaly has not been clarified. This study analyzed the clinical implications and cholangiographic findings of this anomaly. METHODS: A total of 18 patients (15 men, 3 women; median age, 51 years) with an ectopic opening of the common bile duct in the duodenal bulb were studied. Medical records, endoscopic findings, and cholangiographic and other radiographic findings were reviewed. RESULTS: All 18 patients had biliary pain; 7 had fever and chills. Fifteen (83%) had diffuse dilatation of the extrahepatic bile ducts with or without intrahepatic bile duct dilation. Associated bile duct stones were found in 10 (56%) patients. The papilla in the bulb had an orifice stained with bile at endoscopy, which was associated with duodenal ulcer disease found in 13 (72%) patients. The distal end of the common bile duct was tapered and narrowed and had a hook shape in all patients. CONCLUSION: An ectopic opening of the common bile duct in the duodenal bulb may be associated with clinical entities such as recurrent or intractable duodenal ulcer, choledocholithiasis, or acute cholangitis. Although these openings are rare, knowledge of the endoscopic and radiographic findings of an ectopic opening of the common bile duct in the duodenal bulb may help to clarify the cause of chronic recurrent duodenal ulcer disease in some patients and prevent damage to the bile duct during surgery.

[Short common bile duct or high implantation. Apropos of 2 cases].

The authors report a case of so-called short common bile duct or highly implanted common bile duct, associated with double duodenal ulcer, with an unfavourable course in a very young girl. The pathological characteristics and the course suggested it was a congenital case of short bile duct, which is a rare disease, as 37 cases have been reported over a period of 25 years. 32 were associated with duodenal ulcer, which is often resistant to medical treatment, and becomes complicated in 33% of cases. The relationship between the two conditions remains hypothetical. Biliodigestive reflux was the first sign in 66% of cases. Retrograde opacification of the bile ducts under duodenoscopy should permit a diagnosis and precise pre-operative assessment. The abnormality has no special treatment, but the treatment of the associated disease, of the ulcer in particular, should be adapted to the ectopic bile duct to avoid serious injury. At operation, careful examination before dissection will determine the [site] of the papilla and of the opening of the biliary and pancreatic ducts. Vagotomy should be associated with a drainage operation, if possible, or gastrectomy may be performed with gastro-jejunal anastomosis leaving behind the posterior ulcer. Many precautions are necessary including the duodenal stump and details of these are given here.

Suture material as a nidus for formation of common bile duct stones.

Three patients in whom recurrent common bile duct stones formed around suture material used in the region of the biliary tree are reported. Experimental and clinical evidence from the literature is presented to support recommendations that only absorbable ligature and suture materials should be used in the region of the common bile duct.

Ultrastructural localization of type IV collagen, laminin and prolyl hydroxylase in biliary epithelial cells of rat liver following ligation of the common bile duct.

Type IV collagen and laminin are major components of basement membrane (BM), whereas prolyl hydroxylase (PH) is a key enzyme in the hydroxylation of proline to hydroxyproline in collagen synthesis. In order to elucidate the exact mechanism of the formation of BM, immune electron microscopic observation of type IV collagen, laminin and PH was made in rat liver with marked proliferation of bile ducts following ligation of the common bile duct. Extracellular localization of type IV collagen was found in the BM of bile ducts and blood vessels and in the space of Disse in both normal rat liver and the liver of rats undergoing operation. Type IV collagen was localized in lamina rara and lamina densa. Laminin was codistributed with type IV collagen in BM but rarely in the space of Disse even in the liver of rats undergoing operation. Immunostaining of laminin was diffusely spread in lamina densa, but sparsely in lamina rara. Though no reaction products of type IV collagen and laminin were detected in the cytoplasm of normal biliary epithelial cells, they were found in rough endoplasmic reticulum (rER) and the vesicles close to the basal surfaces of the plasma membrane of the proliferating biliary epithelial cells. No evident localization of these components in Golgi apparatus was found. PH was found in rER of the biliary epithelial cells, hepatocytes, endothelial cells of vessels, fibroblasts and perisinusoidal cells except for Kupffer cells in normal rat liver. More intense and diffuse staining of PH was observed in rER in the proliferating biliary epithelial cells of the liver of rats undergoing operation in concomitance with the evident localization of type IV collagen in this organelle. These findings suggest that the major components of BM, such as type IV collagen and laminin in the proliferating biliary epithelial cells, are produced in rER and secreted by vesicles to the basal extracellular spaces, thus forming new BM in these circumstances.

Non-operative removal of retained stones in the common bile duct.

A method of removal of retained common bile duct stones under radiological control is described and its use in 16 patients reported. The ease of the method, the minimal associated morbidity and the inexpensiveness of the equipment suggest that this should be the primary method of removal of retained stones when a T tube has been placed into the common bile duct.

Percutaneous placement of biliary stents for the treatment of high risk patients with jaundice due to common bile duct stones.

OBJECTIVE: Percutaneous treatment of eight high risk patients with jaundice due to common bile duct stones who were unfit for, or refused surgery and in whom endoscopic therapy failed. METHODS: Fine needle percutaneous cholangiography was followed by catheterization of the bile duct and insertion of a 10-Fr double pigtail Teflon stent in seven cases and a metal stent in one patient with bile duct stones and noncalculous lower common bile duct obstruction. RESULTS: Stent insertion was successful in all patients. Two patients showed pus in the common bile duct. Stent insertion in these relieved the jaundice, but one patient died from sepsis at 72 h. The other patient died from renal and respiratory failure 3 wk after stent insertion with resolution of the jaundice. In six patients, stent therapy relieved the jaundice for periods up to 3 yr or death from other causes. CONCLUSIONS: These findings suggest that percutaneous transhepatic stent insertion is a reasonable alternative for the management of common bile duct stones when endoscopic stent insertion fails.
